[PATCH v2 0/2] common: Move exit related functions to common/exit

[PATCH v2 0/2] common: Move exit related functions to common/exit

[Nirjhar Roy (IBM)]

This patch series moves all the exit related functions to a separate file -
common/exit. This will remove the dependency to source non-related files to use
these exit related functions. Thanks to Dave for suggesting this[1]. The second
patch replaces exit with _exit in check file - I missed replacing them in [2].

[v1] -> v2
 - Removed redundant sourcing of common/exit from common/{btrfs,ceph,dump,ext4,populate,punch,rc,repair,xfs}. Thanks to Zorro for pointing this out.
 - Moved the sourcing of common/exit in common/preamble from the beginning of the file to inside the function _begin_fstest()
 - Moved the sourcing of common/exit in check script from the patch 1 to patch 2 since patch 2 uses _exit().
 - Replaced exit() with _exit in the trap handler registration in the check script. Thanks to Zorro for pointing this out.

[PATCH v2 1/2] common: Move exit related functions to a common/exit

[Nirjhar Roy (IBM)]

Introduce a new file common/exit that will contain all the exit
related functions. This will remove the dependencies these functions
have on other non-related helper files and they can be indepedently
sourced. This was suggested by Dave Chinner[1].

Sorry, I didn't notice this earlier. A similar change[c1] was already 
posted by Dave.

Neither of my replys to v1 made it to the list [1], so I'll have to
repeat what I said here.

I did point out that I had already sent this out here:

https://lore.kernel.org/fstests/20250417031208.1852171-4-david@fromorbit.com/

but now this version is mostly the same (except for things noted
below) so I'm good with this.

This isn't needed. Include it in check and other high level scripts
(which need to include this, anyway) before including common/config.

This should be removed and replaced with _fatal

> +{

And this should be removed as well. 

i.e. These two functions are only used by common/punch, so change
them to use _fatal and _exit rather than duplicating the wrappers.

Please leave a blank line between includes and unrelated code.

Please add a comment explaining that _exit will capture $status
that has been previously set as the exit value.

Realistically, though, I think 'exit $status' is much better here
because it clearly documents that we are capturing $status as the
exit value from the trap rather than having to add a comment to make
it clear that $status is the exit value of the trap...

Yeah, I will use "exit \$status" and mention in comments as to why we 
aren't using _exit(), although we can.
